D7-D0 are the data values to be loaded into the Tap Register to set the wiper position, while D8 is
used to set the output mode. D8 has to be loaded into the NVMEM0~3 first and then the “Load Tap
Register” command (#6) has be executed to load D8 into the output-selection MUX to set the output
mode. D8=0 sets the output to Buffer Off mode while D8=1 sets to Buffer On mode.

Note:
• A multiple of 24 bits must always be sent or the
command will not be valid
• Bits marked ‘x’ are don’t care bits.
R/B goes LOW at completion of commands
2, 4, 5, 6 and 7 to allow NVMEM to program
for TSV. For other commands, R/B stays
HIGH after command is sent.
